A giant banner unfurled over Kiev’s central Maidan Square last week: an enormous broken chain stretched from black smoke, symbolizing the revolution that took place in this very place three years ago, and stretched through broken links to the blue sky: Ukraine’s happy future with Europe. For a country at war, the message was important. For a country about to host the Eurovision Song Contest, a phenomenon embraced and celebrated by millions every year, including gays who have seen LGBT artists win repeatedly, the symbolism was more important still.
